The Lowdown
Right off the bat, the surf is on the small side at Jaconé. Thursday morning’s got a bit of waist-high swell from the ENE at 5ft, but the period is short, only 7 seconds. It’s clean with that light cross-offshore breeze, but it’s not going to get the heart pumping. The water temp is sitting at 73°, which is pretty average for this time of year, so no surprises there.
The rest of Thursday and all of Friday are pretty flat and ordinary. We’re looking at knee-high dribble. Saturday morning bumps up slightly to 3ft, but the period drops to 6 seconds, so it’s just chop. The afternoon is a different story though – the swell jumps to 3ft but the period balloons to 17 seconds, and the energy jumps to 1021. It’s a long-period groundswell, but with a cross-offshore wind it might be a bit tricky. Still, it’s the first sign of life.
Then we get to Sunday the 9th. This is the standout. Morning brings in a solid 7ft of SSW groundswell with a 13-second period. The energy is pumping at 1449. With a light offshore NNE wind, it’s going to be clean and powerful. This is the one for experienced surfers. It’s a proper session. The afternoon gets blown out by a strong onshore WSW wind, so get out there early.
Monday and Tuesday look messy. The swell stays around 7ft to 8ft, but the wind is cross-onshore and it’s choppy. Not worth paddling out for. Wednesday the 12th cleans up again with a cross-offshore breeze and 6ft of swell, but the energy drops a bit. It’s good, but not as good as Sunday.
Thursday the 13th morning is another cracker. 7ft of S swell at 13 seconds, light offshore NE wind, and a combined energy of 1305. This is right up there with Sunday. Clean, strong, and organized. The afternoon stays clean but the swell backs off a touch.
The following week, from the 15th onward, things get a bit inconsistent. There’s still swell in the water, mostly in the 5ft to 8ft range, but the winds are variable. The 16th has a clean morning with 4ft, and the 17th has a strong offshore wind but the swell is shorter period. From the 18th through the 21st, it fades out. The swell drops below 3ft and it’s mostly knee-high slop. The 19th does have a glassy morning with 3ft, but it’s weak.
So, to sum it up: the two true standouts are the mornings of Sunday the 9th and Thursday the 13th. Both have solid groundswell, good energy, and offshore winds. Everything else is a bit of a mixed bag. The first week has the most potential, the second week is more of a waiting game.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
